I've upgraded to 2.2.2 and am doing some basic modifications to the code base... minor tweaks at this point.

One thing I would like to do is to adjust the right side bar (e.g., reorder, subtract items, etc.).

However, I'm unclear what the rationale for the new design is. It seems to be using a plugin now. I've become lost in the code. The plugin architecture has complexity that seems disproportionate to what one would expect when making a minor change in the presentation logic on the sidebar. Can anyone sketch a map?
